[Question] Sorting map keys in bstr wrapped is expected?

[kentakayama]

With core deterministic encoding, the keys in every map MUST be sorted, but does it applied to bstr wrapped maps?
The diag2diag tool doesn't sort them, but I'm not sure whether it behavior is correct.

The keys in every map MUST be sorted in the bytewise lexicographic order of their deterministic encodings.

testfiles

• test.cddl

start = bstr-wrapped-map / zero-one-map
bstr-wrapped-map = bstr .cbor zero-one-map

zero-one-map = {
    ? zero => int,
    ? one => int,
}

zero=0
one=1

• body.diag

{e'one': 1, e'zero': 0}

• wrapper.diag

<< ref'body.diag' >>

test commands

Keys are not sorted in bstr wrapped map even with -d option.

$ CBOR_DIAG_CDDL=test.cddl diag2diag.rb -e -d -ae -aref body.diag
{0: 0, 1: 1}
$ CBOR_DIAG_CDDL=test.cddl diag2diag.rb -e -d -ae -aref wrapper.diag
<< {1: 1, 0: 0} >>

my preference

Keys are sorted also in bstr wrapped map.

$ CBOR_DIAG_CDDL=test.cddl diag2diag.rb -e -d -ae -aref body.diag
{0: 0, 1: 1}
$ CBOR_DIAG_CDDL=test.cddl diag2diag.rb -e -d -ae -aref wrapper.diag
<< {0: 0, 1: 1} >>
